Renewables Provided 98 percent of all New U.S Generating Capacity
“Is it true that 98 percent of all newly generated energy in the U.S now comes from renewables?”
Some astonishing news has just come out. In a recent report by the U.S. Federal Energy Regulatory Commissions (FERC), 98 percent of all new energy generating infrastructure built in the U.S during the first two months of the year came from renewable sources! This is a massive step forward for sustainability and shows current administrations the power of renewable energy.
The Rosenfeld Effect
“Why do some U.S states like California have a much lower energy consumption rate than others?”
Hello everyone, in honor of my recent acceptance to work in the buildings energy department at Berkeley Lab, I’ve decided to write about one of its most important humanistic accomplishments.
In the midst of the 1970s, there was an energy crisis happening all around the world. In response to the outcome of the 1973 war, OPEC states had begun an oil embargo to the U.S and its allies. This caused energy prices to skyrocket and supply to dwindle, having tantalizing effects on the world economy. In the U.S, these wounds were worsened by the continuous increase in energy that had been running for decades. Governments had looked to all sorts of solutions. In California, then (and now present) Governor Jerry Brown was considering building a series of new power plants to revive energy production. But he was soon approached by a prominent scientist from Lawrence Berkeley National Laboratory named Arthur Rosenfeld, who had a completely different but more logical solution. Instead of creating more energy production, why not simply consume less of it? Once adopting this idea, the state of California experienced something very peculiar. As the energy consumption of the rest of the nation rose with time, its own energy levels have stayed relatively flat since the 1970s! This empirical fact is known as The Rosenfeld Effect and is a prominent example of the success of energy efficiency.
How Climate Change will Make Renewable Energy Adoption in the Caribbean More Difficult
“How will Climate Change make renewable energy adoption in the Caribbean More Difficult?”
Caribbean Nations are doing their part to combat Climate Change by adopting renewable energy. However, this will become more difficult as global temperatures rise, since the increased frequency of rainfalls and hurricanes make installations more difficult. But by adopting climate change adapted technology such as hurricane-resistant wind turbines, the Caribbean will be able to build itself into sustainability.
A New Design for Hurricane Resistant Wind Turbines
“How can we make turbines dedicated to withstanding hurricanes?”
Although offshore wind turbines can generate much greater amounts of energy than normal during hurricanes, the storm conditions can be disastrous to their structural integrity. This has prompted researchers from the University of Virginia, University of Illinois, University of Colorado, Colorado School of Mines, National Renewable Energy Laboratory (NREL), and Sandia National Laboratories to come up with a new design. Taking design inspiration from palm trees, the so-called Segmented Ultralight Morphing Rotor Wind Turbine used downward facing blades that can move flexibly with the advent of strong winds. These blades are also made out of lighter material and the turbines have a simpler construction, allowing for easier assembly. Testing on these units will begin in the U.S State of Colorado this Summer, hopefully with exciting results.
How Climate Change Will Affect Renewable Energy Adoption in the Caribbean
“How will the Caribbean renewable energy adopters react to climate change?”
Climate change is affecting the world everywhere, but the Caribbean might be one of the most impacted. Their scattered geography makes them reliant on oil imports for energy, only further exacerbated by their aged grid systems in drastic need of repair. Climate change threatens to destroy the livelihood of these nations with worsening rainstorms and hurricanes, as seen in Puerto Rico. Caribbean policymakers are taking proactive measures to prevent further catastrophes by installing distributed renewable energy to increase their nation’s climate resiliency.
New York State’s New Energy Efficiency Target
“What does New York’s new energy efficiency target entail?”
In recent news, New York Governor Andrew M. Cuomo has launched an ambitious energy efficiency plan for his state. New York civil infrastructure and policy will now be structured such that the state will reduce 1/3rd of the greenhouse emissions. Earth Day will be used as the annual marker for energy reductions.
Mixed Turbulent Laminar Flow
“What happens when a fluid flow neither turbulent nor laminar?”
Fluids are usually thought of having either turbulent or laminar flow. However, it is possible to exhibit both characteristics, making it in the Mixed Turbulent Laminar Flow. This usually happens when a fluid enters a plate and has a Reynolds Number between 5*10^6 and 1*10^7.
